Fully updated to reflect new developments in the field, the Fourth Edition of Introduction to Optimization fills the need for accessible treatment of optimization theory and methods with an emphasis on engineering design. Basic definitions and notations are provided in addition to the related fundamental background for linear algebra, geometry, and calculus.
This new edition explores the essential topics of unconstrained optimization problems, linear programming problems, and nonlinear constrained optimization. The authors also present an optimization perspective on global search methods and include discussions on genetic algorithms, particle swarm optimization, and the simulated annealing algorithm. Featuring an elementary introduction to artificial neural networks, convex optimization, and multiobjective optimization, the Fourth Edition also offers:
 A new chapter on integer programming
 Expanded coverage of onedimensional methods
 Updated and expanded sections on linear matrix inequalities
 Numerous new exercises at the end of each chapter
 MATLAB exercises and drill problems to reinforce the discussed theory and algorithms
 Numerous diagrams and figures that complement the written presentation of key concepts
 MATLAB Mfiles for implementation of the discussed theory and algorithms (available via the book's website)
